Chrysanthemum plant named &#39;Zanmugoldru&#39;

ABSTRACT

A  chrysanthemum  plant named ‘Zanmugoldru’ characterized by its small sized blooms with yellow ray florets and prolific branching; natural season flower date October 8 (week 41); blooming for a period of 5 weeks.

BOTANICAL DESIGNATION

Chrysanthemum×morifolium Ramat.

CULTIVAR DENOMINATION

‘Zanmugoldru’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially grown as a garden mum, and herein after referred toby the cultivar denomination ‘Zanumgoldru’. ‘Zanmugoldru’ is a productof a breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new chrysanthemum cultivars with adouble type flower, a natural season flower date around October 8 (week41); blooming for a period of 5 weeks. ‘Zanmugoldru’ is a seedlingresulting from a crossing of the seed parent id 995 and the pollenparent id 710. Plants of the new cultivar ‘Zanmugoldru’ differ fromplants of the parents mainly in natural-season flowering (1) and flowercolor (2). (1) The plants of the seed parent flower in early season,while those of ‘Zanmugoldru’ in late season. (2) The flowers of thepollen parent are more pale yellow than those of ‘Zanmugoldru’

The new and distinct cultivar was discovered and selected as a floweringplant by Wilhelmus Bemardus Blom on a cultivated field in Rijsenhout,The Netherlands in 2005. The first act of asexual production of‘Zanmugoldru’ was accomplished when vegetative cuttings from the initialselection in 2005 were propagated further in a controlled environment inRijsenhout, The Netherlands. The new cultivar has been found to retainits distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum isshown in the accompanying drawings, the color being as nearly true aspossible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown outdoor in DeMotte, Ind., USA, under natural day length and temperature andplanted in week 25 in 2007. The natural blooming date of this crop wasOctober 8 (week 41) . The average height of the plants was 30 cm. Nogrowth retardants were used. No tests were done on disease or insectresistance or susceptibility. No tests were done on cold or droughttolerance. This new variety produces small sized blooms with yellow rayflorets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmugoldru’ is ‘Castor’ (U.S. Plant Pat. No 14,612.).When ‘Castor’ and ‘Zanmugoldru’ are being compared the followingdifference is noticed: The difference of ‘Castor’ and ‘Zanmugoldru’ are(1) Flower size. And (2) Color flower center (1) The flowers of ‘Castor’are larger in size than those of ‘Zanmugoldru’ (2) The flower center of‘Zanmugoldru’ are more orange colored than those of ‘Castor’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmugoldru’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
